As a general rule I wouldnt go, going to a place surrounded from her friends judging you, her orbiters fighting for her attention and trying to sabotage you while you stand there alone with no backup or friends.
Thanks but I pass on such things.
I remember once when a girl invited me to a party with her friends and thankfully I didnt go, saw the pictures on facebook 3 days later and it was her, her two female friends and about a dozen of guys clearly fighting for a piece of cake in every picture.
Downgraded her from potential date to potential fvck buddy same day just because she tought I was orbiter material, no resources invested in her at all any more.
